I always come on here asking for advice and never try and help anyone so this is me giving back lol I have recently gotten bad acne around my mouth and I didn't know what it was from but I figured either birth control or stress. I started taking vitamin D on Saturday and it is now Wednesday and my skin is so much better it was like a miracle. I'm not saying it's a cure all but it helped me and I'm hoping that it doesn't pop up around my period but it can't help to keep taking it. I hope this helps someone. I never had bad skin and it made me hide from everyone and I don't want anyone to feel the way I felt when I had it so I hope it helps someone ! P.s. try and get it from a supplement place and not the ones from drug stores because those are usually not as effective. Good luck! xoox
